REVERSIBLE LOCK-CASING AND KEEPER FOR COIN-CONT-ROLLED LOCKS.

Original application No. 83,820, filed March 13, 1916. Divided and thisapplication Serial No. 109,126.

To all whom it may concern:

Be it known that I, GEORGE G. F. BOSWELL,-

and exact description thereof, reference being had to the accompanyingdrawings, in which like letters refer to like parts.

The invention set forth in this application for Letters Patent relatesto reversible lock cases and keepers and covers subject matter dividedout of the former application of the applicants, Serial #831,820, filedMarch 13th, 1916.

The object of this invention is to construct a lock case and keeper insuch a way that they will be reversible, and arrange the parts so as toprevent the bolts of coin controlled looks from being picked. Thisobject is ac complished by having a flange extending from the lock caseso as to project over or overlap the keeper into which the lock boltenters when thedoor is closed. This prevents the picking of the look byinserting an instrument between the keeper and the 1loorik case into thelock to move and open the The full nature of the invention will beunderstood from the accompanying drawings and the following descriptlonand claims.

In the drawings, Figure 1 is an elevation of a portion of a door anddoor frame with a coin controlled lock thereon and the door closed, thelock being at the left-hand edge of the door. Fig. 2 is the same withthe lock reversed and placed at the right hand edge of the door. Fig. 3is a central vertical section through the lock. Fig. 4 is a crosssection through the lock and bolt showing the case overlapping thekeeper so that the door may open outward. Fig. 5 is the same as Fig. 4only reversed so that the door may open inward instead of outward andthe keeper overlap the case. Fig. 6 is a detail perspective view of aportion of the lock frame. Fig. 7 is a sectional View thereof on line77, Fig. 6.

There is shown in the drawings in Fig. 1 a door 10 with a lock on theleft-hand edge thereof engaging a keeper 11 on a part of the door frame12. v In Fig. 2 the lock is at Specification. of Letters Patent.

the right-hand edge of the door instead of the left. The lock casing 13'consists of a single case forming the front, sides and top and with theback open and adapted to be secured to the door so that the door closesthe back of the casing. None o'f the mechanism is mounted on the door,but instead it is all mounted in the casing so that when the casing isremoved, all of the lock mechanism is mounted in-connection with thatone part of the casing instead of being mounted 011 a plurality of partsof the casing, as heretofore. This enables the lock mechanism to berigidly mounted and be accessible for repalrs or manipulation.

The casing has an operative flange 14 on both sides thereof whichsurrounds, envelops and overlaps the inner end of the keeper so thatwhen the door is closed and looked, a person cannot insert anyinstrument between the keeper and the case and thus get into the lockand move the bolt to open the same. The flanges on both sides enable thecasing to cooperate with the keeper and to accomplish this end wheneverthe lock is reversed regardless of the position in which it may bemounted. A modified form is shown in Fig. 5 where there is a flange 15on the outer portion of the keeper 11 instead of a flange being locatedon the outer part of the casing. The purpose of this construction is toadapt the lock to the door if it swings inwardly. The constructionpreviously described and shown in Fig. 1 is adapted for a door whichswings outwardly. It is immaterial whether the flange .14 for protectingthe look from picking projects beyond the main surface of the case ornot so long as there is a surface of the case which overlaps the keeper.

The case has a counter slot 16 in its upper end, a coin inlet slot 17below it, a porter key hole 18, an outside knob 19, a removable door 20and the coin chamber, as shown in Fig. 1.

There is shown in Fig. 4: a bolt 25 which has a vertical andlongitudinal slotted portion 26 extending almost to each end thereof andwide enough to receive any of the small coins. The bolt is slidabletransversely of the casing between the two guide ribs 27 and 28 whichextend entirely'across the inner surface of the front wall of thecasing. On each side of said bolt there are two flanges 30 and131 andsaid flanges on the.

two sides of thebolt are opposite each other respectively, as shown inFig. 4. The rear flanges 30 have each a hole through which a guide rod32 loosely projects. The rod 32 is connected with a plate 33, said platebeing adapted to close the bolt opening 34 of the lock casing 13 notoccupied by the bolt. The plate 33 is prevented from assing outwardlythrough the opening 34 by inserting a plate 35 over the opening 34, saidplate 35 having beveled ends which engage dovetailed recesses 14 formedin the end walls of the flange 14. After the plate 33 carrying the rod32 hasbeen properly positioned in one or the'other of the bolt openings34, the plate 35 is entered in the dovetailed grooves of the member 14and when the casing has been attached to the door it will be impossibleto remove said plate 35 until the casing is disengaged from the door.From this construction it will be seen that the flange 14 not onlyserves to prevent the lock from being picked by introducing aninstrument between the keeper and the casing, but serves as a retainerfor'the cover plate for the bolt opening not in use, and that said coverplate can be used at either side of the lock casing. A spiral spring 36surrounds the rod 32 and bears against the flange 30 for throwing thebolt and holding it in looking position. Said spring is compressed whenthe bolt is retracted. Both flanges 30 have a hole in them toreceive'said rod 32 so that the bolt can be reversed, as shown in Fig.5, depending upon whether the. door is to move outward, as shown in Fig.4, or to move inward, as shown in Fig. 5.

On the front face of the lock case surrounding the slot 17 is a coinmeasuring frame having on one side thereof an openthe lock is removedwhereby a coin of a oer-- taln denomination only, may be insertedthrough the slot 17.

The invention claimed is: I

1. The combination with a door frame, and a. door, of a keeper'on thedoorframe,

a lock on the door having a bolt adapted to enter said keeper, acasewith a bolt opening on the opposite sides thereof, and a flange.

surrounding each of said bolt openings so 4 as to overlap the keeper onits top and bottom faces and its outer face, substantially as setforth.

2. The combination with a door, of a lock casing, consisting of a singlemember open at the back and secured to the door, said door acting as aback plate for the casing, said casing having a bolt opening on oppositesides thereof, a flange extending around three sides of said opening,and means 00- operating with said flanges to close either bolt opening.

3. The combination with a door frame and a door, of a lock casing havinga bolt opening on opposite sides thereof, a flange extending aroundthree sides of said opening, each flange having dovetailed grooves and aplate having beveled ends for cooperation with said dovetailed groovesadapted to cover either of said bolt openings.

In witness whereof, I have hereunto affixed my signature. I

GEORGE G. F.'BOSW'ELL.
